Anyone have any luck getting this feature working correctly?? I cant seem to get it working right, objects are switching in and out when they should be visible in the viewport.

I checked the sphere data by creating wireframe spheres from the same data I am sending this function. The spheres are in the right spot.

I test the returned DWORD and render the object if any of the Inside flags or Intersection flags are set or the HRESULT is !D3D_OK.

what gives???
